.SH "DESCRIPTION"
.sp
The Reservation Report command returns a Reservation Status data structure to host memory that describes the registration and reservation status of a namespace\&.
.sp
The size of the Reservation Status data structure is a function of the number of controllers in the NVM Subsystem that are associated with hosts that are registrants of the namespace (i\&.e\&., there is a Registered Controller data structure for each such controller)\&.
.SH "OPTIONS"
.PP
\-n <nsid>, \-\-namespace\-id=<nsid>
.RS 4
Retrieve the reservation report structure for the given nsid\&. This is required for the character devices, or overrides the block nsid if given\&.
.RE
.PP
\-d <num\-dwords>, \-\-numd=<num\-dwords>
.RS 4
Specify the number of Dwords of the Reservation Status structure to transfer\&. Defaults to 4k\&.
.RE
.PP
\-e, \-\-eds
.RS 4
Request extended Data Structure: If this bit is set to a
\fI1\fR, then the controller returns the Extended Data Structure\&.
.RE
.PP
\-b, \-\-raw\-binary
.RS 4
Print the raw buffer to stdout\&. Structure is not parsed by program\&.
.RE
.PP
\-o <fmt>, \-\-output\-format=<fmt>
.RS 4
Set the reporting format to
\fInormal\fR,
\fIjson\fR
or
\fIbinary\fR\&. Only one output format can be used at a time\&.
.RE
.PP
\-v, \-\-verbose
.RS 4
Increase the information detail in the output\&.
.RE
.PP
\-t <timeout>, \-\-timeout=<timeout>
.RS 4
Override default timeout value\&. In milliseconds\&.
